Research on Detection and Maintenance Techniques for Power Relay Protection Faults
This paper discusses the working principle,fault types,fault detection and maintenance strategies of power relay protection.In the first step,the working principle of power relay protection is introduced,and the possible faults can be monitored and handled in real time by comparing the parameters such as current,voltage and power of the system.In the second step,the common fault types of power relay protection are expounded in detail,including short circuit fault,overload fault and grounding fault.Thirdly,different fault detection technologies are studied,such as fault detection technology based on current differential principle,voltage differential principle,power direction principle and impedance spectrum analysis,which can effectively detect and locate faults in power system.The fourth step discusses the fault maintenance strategy of power relay protection,including fault diagnosis method,fault location method and fault maintenance strategy design,which is of great significance to improve the safety and stability of power system.
